OIL-CAN.

SPECIFICATION. forming part of Letters Patent No. 306,027, datedSeptember 30, 1884.

Application filed August 16, 1884.

T aZZ whom it may concern.-

Be it known that 1, MICHAEL A. W. LoUIs, of Washington, in'the Districtof Columbia, have invented certain new and useful Improvements inOil-Cans; and I do hereby declare that the following is a full, clear,and exact description thereof.

My invention relates to oilers or oil-cans; and it consists in certainpeculiarities of construction, all as will be more fully set forthhereinafter.

In the drawings, Figure 1 is a vertical central section of my entiredevice. Fig. 2 is an inverted view of the nozzle, also in section, andturned one-quarter around. Figs. 3 and at are sectional views of amodified construction, and Fig. 5 is a sectional view of a curved nozzlefitted with my improvement.

The object of my invention is to provide a device for cleaning andclearing the interior of the nozzle, and which shall act automaticallyandwholly by gravity, and one wholly free from springs. I-Ieretoforeindevices intended to accomplish this object a serious obj ection hasarisen when springs were employed, and when levers were used, havinghandles or stems extending outside of the can or noz- 'zle, as theopenings for the latter were liable clearly shown in Fig. 2.

to leakage, besides admitting dirt, and the springs were liable to getout of order, to become clogged and inoperative, and to add veryconsiderably to the expense.

A is an oil-can or oiler of ordinary construction, and preferably ofgenerally conical shape, into the apex of which a spout or nozzle, B, isinserted by any usual means-as by a screwthreaded construction of theadjacent parts. At any convenient point-say near the base of thenozzle-a bar, C, is secured, having a central perforation, c, and whichbar is of only such width as is required for the said perforation,leaving free oil-passages on each side of it, as

D is a needle or pointed wire, which passes through the perforation c,and which has, in its preferred form, a weight, D, attached to its base,and above the bar 0, when the parts areput together, a stop, d. Thisneedle is of sufficient length so that when the can is in (No model.)

one position its pointed end shall be just below the tip or dischargeend of the nozzle, and when the can is in the opposite position justabove the said tip, projecting through the same.

As stated, the operation of the device is wholly automatic, thereversing of the can in oiling or the restoration of the can to itsnormal position being sufficient to permit the needle to do its workunder the force of gravity.

In Figs. 1, 2, and 3 I show the simplest and cheapest form of my device,the last-named figure merely showing it applied to a curved nozzle; butin some instances it may be desired to have the needle protrude abovethe tip of the nozzle when the can is at rest on its bottom, and toaccomplish this I have shown in Figs. 4: and 5 a slightly-modifiedconstruction. In this form I provide the bar C with a secondperforation, 0, between its central perforation, c, and the end of thebar, and pass a short rod or wire stem, 0 having a head, a, through thishole, and to the lower end of this rod I pivot one end of abent wire,

0*, which passes through a hole or loop at the base of the needle D, andbears at its-other end the weight D. Inthis form for the stop d, Iemploy a loop depending from the under side of the bar C, and throughwhich the wire 0 passes, as shown.

The operation of my device is exactly the same, no matter which form Iusethat is, by gravity and automatic. Of course my device would worksatisfactorily if the bar C were placed below the base of the nozzle orhigher up in the nozzle; but I have found by experiment that the presentlocation is the most satisfactory in the majority of instances.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. An oil-can having a cleaning -needle passingthrough the nozzle, andweighted at its base, and passing through a suitably-perforated support,all the operative parts being wholly within the can and adapted tooperate solely by gravity, substantially as set forth.

. 2. In an oil-can, the combination of the nozzle B, bar C, andcleaning-needle D,weight-' ed at its base, and adapted to move up and-Intestimonythatl.elainitheforegoinglhave clown through a perforation inthe saiclbar hereunto set my hand, at Vashington, in the IO by the forceof gravity, substantially as set District of Columbia, in the presenceof two forth. witnesses.
